The Tyfo® Fibrwrap® Pipe <strong>Rehabilitation</strong> System is a Fiber-Rein<strong>for</strong>ced Polymer<br />
(FRP) method, utilizing carbon fiber, <strong>for</strong> the repair, strengthening and retr<strong>of</strong>it <strong>of</strong><br />
corrosion-damaged and distressed large diameter PCCP, RCCP, and steel pressure<br />
pipelines used in municipal, industrial and other applications. It’s main use has<br />
been <strong>for</strong> PCCP water and <strong>for</strong>ce mains that have broken prestressed wires.<br />
• Restoration <strong>of</strong> pipelines structural integrity to original load bearing<br />
capability (pressure and external)<br />
• Can be designed to increase pipeline strength over and above original design<br />
• Non-metallic material ensures that corrosion-related damages do not recur in<br />
rehabilitated pipe segments<br />
• NSF 61 certified system <strong>for</strong> potable water<br />
• Thin liner minimizes any loss <strong>of</strong> flow capacity<br />
• Limited to sectional repairs as cost can be high<br />
• Requires highly trained and experienced technicians to work in confined<br />
space with volatile chemicals<br />
• Surface preparation <strong>for</strong> good bond extremely important<br />
• Joint termination is an evolving technology<br />
• No standardized design approach<br />
